I have had my new build for around 2 months and have been getting crashes from the very start whilst playing games. I have recently been in contact with the company that sold my the card and they said to do the latest VBIOS update for the card - so they sent me the link

After completing the update I can no longer see anything on my screen. I can still here the windows log on sound but just can't see anything. I have integrated graphics in my mobo which I can use to still access my computer and was wondering how I can remove this update to get it back to its previous state. Any help would be appreciated thanks.

I'm new to this whole things so explaining this in simple terms would be useful thanks

Then this is what you must do - Using your onbaord vga boot the PC; once in windows go to control panel / programs and features / select AMD Catalyst Install Manager / Change / choose express uninstall / reboot

next

shut down the PC

Once you have done this - and the PC is switched switch off the power suppy [unplug at the wall]

next

reinstall the Radeon 7850 HD OC gfx into the PC in to the PC

boot the pc,

answer this question: then at this point do you still have a black screen?

Even if i have the vga into the motherboard while the graphics card is connected to the power supply it doesn't display, so will i take the graphics card power cable out put main boot as onboard then plug it back in??
